GRAIN-SEPARATOR.

SPECIFICATION forming part of LettersPatent No. 254,270, dated February 28, 18.82,

' Application filed July 22, 1831. (Model.)

' To all whom it may conce-rn:

'of holes, i', in the outer arm of a bell-crank le-l Be itknown thatI, JOHN BRUsii-nof thecity of Albany, in the county of Linn and State of Oregon, have invented a new and useful Improvement in Grain Separators, which iniprovement is fully set forth in the following specification, reference beinghad to the accompanying drawings, in which- Figure 1 is a perspective view of my improved grain-separator. Fig. 2 is a longitudinal central section of the same, and Fig. 3 is a detail view.

My invention relates to improvements in grain-separators; and it consists in the peculiar arrangement and construction ot the parts, as hereinafter more fully set forth.

In the accompanying drawings, a represents the frame of my improved grain separator, which frame is of the usual construction and provided with a hopper and a fan, b, having a pinion, c, on its aXle, which engages with a larger pinion, d, on a crank-shaft, e, journaled in one of the sides of the frame, whereby a rapid rotary motion is imparted to the fan.

To one end of thefanshafte',journaled inthe sides of the frame, is secured a disk, f, provided with three or more holes, g,near its circumference, into one of which the bent end of the pitman h is inserted, the opposite bent end of the pitman h being inserted in one of a series ver, j, journaled in angular brackets k, secured to one ofthe posts of the frame of the separat-or. l represents an upper, and l an under, shoe situated vertically below the upper shoe. The upper shoe, l, is suspended in the opening in the frame by the opposite hangers Z2 l2, secured to theframeof the machine attheirupperends, and to the upper shoe,nearits bottom, at their lower ends. Similar hangers are employed to suspend the upper shoe on its opposite side. The lower shoe, l', is similarly suspended from each side of thefframe by the hangers Z3 L3.

m'represents an angular plate secured to the upper shoe, l, near its bottom, and provided witha series of holes, m,in its horizontal part. n represents an angular plate secured to the t lower shoe near its upper edge and immediately under the angular plate m. The angular plate a has itshorizontal part provided with a series of holes, u. The inner arm of the bellcrank lever j is also provided with a series ot' holes, i. l

0 o represent hooks, each bent at both ends and each adapted to engage in one of theholes in' the inner armot' the bell-crank lever and in one of the holes in the angular plates m n, se-

cured to the upper and lower shoes, whereby more or less transverse throw or oscillation may be imparted to either shoe, as desired, when the shoes are oscillated by turning the crank-shaft e.

p p are hooks bent at each end, the outer ends of the hooks being inserted in holes in lugs p p', attached to the opposite posts on each side of the frame, the inner ends of the hooksp being inserted in holes in lugs p2 p2, secured to the upper and lower shoe. Similar hooks are inserted in similarly-formed lugs in the opposite side of the machine.

q q. represent lugs secured to the bottom of the upper shoe, l, on each side thereof, and projecting from the shoe laterally on each side thereof, and each provided with a hole for the passage of pins i", which pass thence into holes in the upper edges ot' the lower shoe, l', thereby locking theshoes together, when desired.

The longitudinal sides of the upper shoe, Z, are provided with opposite holes near their outer ends, through which passes a rod, t, screw-threaded at one end for the reception of a thumb-nut, t', whereby the sides of the upper shoe may be clamped against the hurdle a when desired, and the inclination of the latter may be varied as desired. The inner faces of the longitudinal sides of the upper shoe, l, are providedv with gains or grooves for the reception of riddles or sieve-frames when the hurdle is removed from the machine, as hereinafter described.

In separating oats from wheat or other grain the hurdle is introduced into the upper shoe and the proper inclination given it, when the hurdle is clamped in the upper shoe by the rod and thumb-nut. The hook coupling the inside IOO less throw or vibration imparted to it than the lower shoe, which will have a longer Vibration than the upper shoe.

For removing chaff from Wheat or other grain the hurdle is removed and riddles or sieves inserted in the gains in the upper shoe, and the lower hook that connects the bell-crank lever with the lower shoe is removed, and also the two upper hooks that connect the upper shoe on each side with the frame, and the two pins r that couple the shoes together are inserted, so that the two shoes form, in eEeet, a single shoe. The remaining hook coupling the shoes with the bell-crank lever may then be adjusted, as described, and the crank-shaft operated to winnow the grain.

What I claim as my invention is- 1. The combination, with the shoe l,frame a, and hangers Z2 l2, the shoe being provided with the angular plate m, having a series of adjusting-holes, m', of the shoel, arranged under the shoe Z, and hangers Z3 Z3, the lower shoe being provided with angular plate n, having adjusting-holes n', bell-crank lever j, provided with aseries of adjusting-holes, coupling-hooks o, and operating mechanism, substantially as described.

2. The combination, with the upper shoe, l, frame a, and hangers l2 Z2, the shoe being provided with the opposite perforated lugs q, of the lower shoe, L', lying under the shoe l, and provided with opposite holesin the upper edges ofthe sides, and pins r, substantially as described, and for the purpose set forth.
